Which of the following options given the correct match w.r.t the disease , its Causative organism and mode of infection ?

Options

A. `{:("Disease","Causative Organism","Mode of infection"),("Pneumonia","Haemophilus influenzae","Vector borne"):}`
B. `{:("Disease","Causative Organism","Mode of infection"),("Malaria","Plasmodium vivax","Bite of female Culex mosquito "):}`
C. `{:("Disease","Causative Organism","Mode of infection"),("Amoebiasis","Enatamoeba histolytica","Faeco - oral route "):}`
D. `{:("Disease","Causative Organism","Mode of infection"),("Ascariasis","Filarial worm","With infected food and water "):}`

Answer

To solve the question regarding the correct match of diseases, their causative organisms, and modes of infection, we will analyze each option step by step.

### Step 1: Analyze the first option - Pneumonia
- **Disease**: Pneumonia
- **Causative Organism**: Haemophilus influenzae
- **Mode of Infection**: Vector-borne (as per the option)

**Evaluation**: Pneumonia is primarily caused by bacteria such as Haemophilus influenzae and Streptococcus pneumoniae. The mode of infection is not vector-borne; it is typically spread through droplet infections or aerosols.

**Conclusion**: This option is incorrect.

### Step 2: Analyze the second option - Malaria
- **Disease**: Malaria
- **Causative Organism**: Plasmodium vivax
- **Mode of Infection**: Bite of the female Culex mosquito (as per the option)

**Evaluation**: Malaria is caused by Plasmodium species, including Plasmodium vivax. However, the vector responsible for transmitting malaria is the Anopheles mosquito, not the Culex mosquito.

**Conclusion**: This option is incorrect.

### Step 3: Analyze the third option - Amoebiasis
- **Disease**: Amoebiasis
- **Causative Organism**: Entamoeba histolytica
- **Mode of Infection**: Feco-oral route (as per the option)

**Evaluation**: Amoebiasis is indeed caused by Entamoeba histolytica, and it is transmitted through the feco-oral route, typically via contaminated food and water.

**Conclusion**: This option is correct.

### Step 4: Analyze the fourth option - Ascariasis
- **Disease**: Ascariasis
- **Causative Organism**: Filarial worm (as per the option)

**Evaluation**: Ascariasis is caused by the roundworm Ascaris lumbricoides, not by a filarial worm. Filarial worms are responsible for diseases such as Elephantiasis (caused by Wuchereria bancrofti). Ascariasis is transmitted through contaminated food and water, similar to the feco-oral route.

**Conclusion**: This option is incorrect.

### Final Conclusion
The only correct match among the options provided is:
- **Amoebiasis**: Causative Organism - **Entamoeba histolytica**, Mode of Infection - **Feco-oral route**.

### Answer: The correct option is the third one.
